When the position sensing module 22 is combined with the housing 30, the signal transmitting member 224 is located on a side of the housing 30 adjacent to the portable electronic device 4; in other words, the position sensing member 222 is disposed away from the portable electronic device 4. Thereby, when the image capturing apparatus 1 performs the collection of the optical image of the object 5, the position sensing element 222 also acquires the optical image and performs the calculation of the moving distance of the image capturing apparatus 1. The position sensing component 222 may collect the optical image without interruption, or the position sensing component 222 may also collect the optical image at intervals.

It should be noted that the location sensing module 22 can only have the function of collecting optical images, and convert the collected optical images into position sensing signals, and transmit them to the portable electronic device 4 through the signal transmission component 224. The portable electronic device 4 performs the calculation of the moving distance of the image capturing device 1; or the position sensing signal generated by the position sensing module 22 according to the collected optical image may also be transmitted to the micro processing unit 28, and the micro processing unit 28 The calculation of the moving distance of the image taking device 1 is performed.

In the foregoing two cases, the position sensing signal transmitted by the location sensing module 22 to the portable electronic device 4 or the micro processing unit 28 does not contain any information about the moving distance of the imaging device 1, that is, the position. The sensing module 22 cannot perform the calculation of the moving distance of the image capturing apparatus 1. However, in actual implementation, the position sensing module 22 may also be a position sensing signal that outputs information including the moving distance of the image capturing device 1.

Further, when the image capturing device 1 includes a plurality of position sensing modules 22, the electronic system can determine whether the image sensing path of the electronic system is skewed or offset according to the position sensing signals output by the plurality of position sensing modules 22, Whether the image sensing path is skewed or offset may be achieved by comparing a plurality of position sensing signals or by comparing a plurality of position sensing signals and digital image signals; thereby, the pixel data to be presented by the digital image signals may be performed. The correction of the position and arrangement enables the pixel material displayed on the display unit 44 to perfectly represent the optical image of the object.

The image taking device 1 may further include a cover 32 mounted on the housing 30. The cover 32 is rotatably pivotally coupled to the housing 30. When the image capturing device 1 is performing the optical image capturing of the object 5, the cover 32 can be rotated to the position of the light transmitting member 18 and the position sensing module 22 as shown in FIG. 1 to FIG. The image device 1 performs the acquisition of an optical image of the object 5. However, when the image capturing device 1 does not perform the optical image collection of the object 5, the cover 32 can be rotated to cover the light transmitting member 18 and the position sensing module 22 to prevent dust adhesion or foreign matter from damaging the light transmitting member 18 or the position. The module 22 is perceived to affect the perceived outcome.

Please refer to FIG. 6 and FIG. 7.

It should be noted that the difference between the two is that the image capturing device 1a illustrated in FIG. 6 includes only a single location sensing module 22a, and the location sensing module 22a further includes an computing unit 23.

The operation unit 23 is electrically connected to the position sensing component 222, and collects the position sensing signal generated by the optical image according to the position sensing component 222 to calculate the moving distance of the image capturing device 1 and transmits the operation result to the micro processing unit 28.

Further, the image taking device 1a illustrated in FIG. 7 further includes a battery 31. Under the condition that the image taking device 1a includes the battery 31, the image capturing device 1a can transmit the digital image signal and the control command by the wireless transmitting and receiving unit 33 and the portable electronic device 4. Further, under this condition, the connecting member 24 and the connecting seat 40 as shown in Fig. 2 can be omitted.

The wireless transceiver unit 33 can be, for example, a Bluetooth transceiver or an infrared transceiver. Of course, the image capturing device 1 does not exclude the communication with the communication unit 48 of the portable electronic device 4 through the Internet to complete the transmission and reception of digital image signals and control commands.

After the image capturing device 1a is paired with the portable electronic device 4 to generate an (electrical) connection, the user can activate the image capturing device 1 through an application installed in the portable electronic device 4, for example, and drive the micro device. The processing unit 28 controls the operational states of the image sensing device 12, the light emitting device 200, the position sensing module 22, and the storage unit 26. The function and related description of each element of the image capturing apparatus 1a are substantially the same as those of the image capturing apparatus 1 of the first embodiment, and will not be described herein. The image taking device 1a can at least achieve the same function as the image capturing device 1.
